ABSTRACT:
Offset printing method wherein ink in the form of screened half-tone dots or pixels and unscreened printing-image elements is applied to a printing surface of a recording medium by means of a printing device; a printing form being generated from signals reproducing a printed image; the printing form being inked with an inking device; and the ink being transferred to the printing surface, upon transport of the recording medium relative to the printing device; the signals being processed in a control device for the printing device; includes, near the printing device and before the printing form is generated on a screen or monitor, forming a copy of the printed image from the signals reproducing the printed image and from signals containing parameters of the printing device; whenever the copy deviates from a desired printed image, manually inputting correction values for local inking into the control device, until the copy corresponds to the desired printed image; and generating the printing form and adjusting the elements affecting the inking with the signals reproducing the desired printed image and from signals containing fixed printing-press characteristics.
